Let’s review circulation in the brain

What is Intracranial Hemorrhage?

• ICH is bleeding inside the skull

11/6/2018

5

Consequences of ICH

• Blood accumulates either within the brain tissue or on the surface of the brain tissue causing compression and cell damage or death.

Types of Intracranial Hemorrhage

EXTRA-AXIAL• Subarachnoid• Subdural• EpiduralINTRA-AXIAL• Cerebellar• Intraparenchymal/Intracerebral• Intraventricular

Causes of Intracranial Hemorrhage

Maternal

Drug usage; including aspirin and illicit drugs

Pre-eclampsia

Placental abruption

Placental alloimmunization

Autoimmune disorders

Causes of Intracranial Hemorrhage

Term Preterm

Mechanical Trauma Hemodynamic Instability

Birth ashpyxia; secondary to ischemia-reperfusion injury

Vascular and Anatomic immaturity

Infection Possibly inflammatory factors

Coagulation abnormality Possibly genetic factors

Vascular abnormality

Cardiac diagnosis that results in increased cerebral venous pressureThrombocytopenia

Symptoms of ICHWill vary according to size and location of

hemorrhage. Will also vary by term vs. preterm infant. Unfortunately, symptoms are non-specific to

ICH.• Cardiorespiratory symptoms: apnea,

bradycardia, hypo/hypertension• Unexplained drop in Hct• Seizures• Bulging fontanelles• Encephalopathic; altered level of consciousness,

absent or weak reflexes, hyper/hypotonia

11/6/2018

8

True of ALL ICHs• True incidence of ICH is unknown.• For all types of ICH, incidence is estimated at 4 per

1,000 live births. The incidence increases for instrumented births (forceps, vacuum).

• Many of the symptoms of ICH are similar and it will be very difficult to distinguish between the types of ICH without imaging.

• Sequelae from ICH will vary depending on the size and location of the bleed in all types.

• Unless hydrocephalus develops, ICH is not identifiable by assessment of the skull.

• It is common for hemorrhages to occur in multiple sites both intra and extra cranial.

“So many layers, so many hemorrhages…”

Diagnostic Imaging in the NICU▪ Imaging provides a noninvasive means to diagnose, screen, and

monitor patients in the NICU

▪ Radiography (X-ray): differentiates densities (air, fat, water, bone, metal)

▪ Ultrasonography (US): converts electrons into mechanical vibrations to create high frequency sound waves within the body –best to compare vibrations of bone and other structures as the sound waves resonate in the body

▪ Computed Tomography (CT): a series of X-rays taken from multiple positions around a single axis to create a composite image

▪ Magnetic Resonance Imaging (MRI): images hydrogen ions in the body (your body is 98% water)

17

Subarachnoid Hemorrhage

11/6/2018

10

Subarachnoid Hemorrhage• Asymptomatic SAH is rarely identified• Symptomatic SAH is usually the result of a medium or large

bleed; most common type of hemorrhage in infants with symptoms.

• More strongly associated with forceps or vacuum-assisted birth.

• Medium sized bleeds may cause seizures. However, 90% of these babes go on to have normal neurodevelopmental outcomes. Blood is reabsorbed, and symptoms resolve.

• Negative neurologic sequela from this type of bleed are very rare.

• If bleed is large, babies appear very encephalopathic, have seizures, apnea and/or bradycardia. They can deteriorate quickly if bleed progresses without intervention.

• Large bleeds can impair flow of CSF, and baby can develop hydrocephalus.


▪ Clinical presentation:

• Most commonly asymptomatic

• Seizure activity on day 2 of life (term infant)

• Otherwise “well-appearing”

• Recurrent apnea (preterm infant)

20

11/6/2018

11


▪ Diagnostic:

• CT scan leads to a diagnosis by exclusion

• LP with uniformly bloody CSF

▪ Outcome:

• 90% of term infants with seizure have normal follow up

21

Subdural Hemorrhage

22

Subdural Hematoma https://www.youtube.com/watch?v=jl_0hgn3Y-w

11/6/2018

12

Subdural Hemorrhage• Most common form of ICH in term infants without symptoms• Usually infants are asymptomatic and bleeds resolve without any

intervention• 2.9% PER 10,000 NSVD vs. 8 – 10% NSVD with forceps or

vacuum• Can be traumatic if lesion/tear is large; can result in brain stem

compression and death• Large lesions within major vessels = baby very encephalopathic at

birth and quickly progresses downward• Small but progressive lesions = Baby may be “fine” 24 hours up to 5

days. Will slowly show signs of neurological deterioration as bleed evolves and/or clot forms; lethargy, irritability, apnea, bradycardia

• Treatment: close surveillance without neurologic signs or surgery may be indicated in large lesions with rapidly increasing ICP

• 80% of infants with SDH have normal outcomes.

Subdural Hemorrhage▪ Diagnostic:

• CT scan

• MRI if the hemorrhage is posterior

• X-ray to determine skull fracture

▪ Outcome:

• Major laceration will result in massive hemorrhage

• Mortality approximately 45%

• Survivors develop hydrocephalus

• Often worsened by close association with HIE

24

11/6/2018

13

Epidural Hemorrhage

• Very rare in term infants• The artery that is the cause of bleeds in

this region is more pliable in neonates and thus much less likely to rupture.

Cerebellar Hemorrhage• More common in preterm infants,

esp. < 750 grams.• Very difficult to ID; not visualized on

head US unless specifically searched • In preterm, cause is similar to IVH. In

term, cause is usually trauma.• Symptoms will be secondary to

brainstem compression; apnea, bradycardia and/or full fontanelles from blockage of flow of CSF.

• Outcome:

• More favorable in term than preterm infants

• Probable neurologic deficits

11/6/2018

14

Cerebellar Hemorrhage

Intracerebellar Hemorrhage

▪ Hemorrhage within the cerebellum resulting from primary bleeding or an extension of bleeding of intraventricular or subarachnoid hemorrhage into the cerebellum

▪ Risk factors: respiratory distress, hypoxic events, prematurity, traumatic delivery

▪ More common in preterm than term infants

▪ Incidence:

• present in 5 to 10% of all neonatal deaths on autopsy

• 15 to 25% of preterm infants < 32 weeks or less than 1500 grams

28

11/6/2018

15



• Catastrophic deterioration with apnea, bradycardia, decreasing Hct

• LP with bloody CSF

• Most common in the first 2 days of life up to 3 weeks of life

29


▪ Diagnostic:

• Cranial ultrasound

• CT to define the hemorrhage

• MRI for definitive diagnosis

▪ Outcome:

• More favorable in term than preterm infants

• Probable neurologic deficits

Intra-axial ICH : Intraparenchymal

• Usually co-exist with a hemorrhage somewhere else in the brain.

• Can be focal or multi-focal

Intraparenchymal Hemorrhage - Stroke

• The term “stroke”, when referring to intraparenchymal hemorrhage, really only applies to term infants.

• Hemorrhagic stroke accounts for 50% of childhood strokes

• However, there is not much literature on hemorrhagic stroke in the infant population

11/6/2018

17

Stroke

• All intraparenchymal/intracranial hemorrhage is stroke, but not all strokes are hemorrhagic.

• The definition of stroke encompasses not only intracranial bleeding, but also non-traumatic subarachnoid bleeds and isolated intraventricular bleeds in the TERM infant.

• Prevalence of hemorrhagic stroke in the perinatal population is 6.2/100,000, with the vast majority intracranial.

• Most hemorrhagic strokes are idiopathic.

Definition• Stroke

– Blockage (ischemic stroke) or breakage (hemorrhagic stroke) of a blood vessel (artery or vein) in the brain.

11/6/2018

18

Hemorrhagic vs. Ischemic

Hemorrhagic Stroke - Outcomes • Neurodevelopmental outcomes for children with

hemorrhagic stroke are poorer than those with ischemic stroke

• Because of limited data on this patient population, statistics are wide-ranging. Mortality for hemorrhagic stroke is estimated anywahere from 5% - 33%.

• Poor neurodevelopmental outcome is estimated at 25% -52%.

• Outcomes are determined by – The size of the stroke– Presence of hydrocephalus– Presence of herniation– Location of the stroke

11/6/2018

19

Periventricular-Intraventricular Hemorrhage (IVH)▪ Occurs once germinal matrix hemorrhage extends into the lateral

ventricle

▪ Risk factors: prematurity (less than 34 weeks), respiratory failure, increasing arterial blood pressure, perinatal asphyxia

▪ Incidence:

• 10 to 15% of infants with hemorrhages

• 30 to 40% of preterm infants <30 weeks or <1500 grams

• 3 times higher risk if <28 weeks

• 2 to 3% of term infants

37

38

So why are

preemies at high risk?!

11/6/2018

20

39

This is what we

are working with…

Intraventricular Hemorrhage - Term• Very rare.• Source of the bleed differs from that of

preterm infants.• Coagulopathy and trauma play a bigger role

in the cause of IVH bleed in the term infant vs. preterm infant.

• Seizures are a symptom in 50 – 65% of cases.

• Approximately 50 % of infants have normal neurologic outcomes.

11/6/2018

21

Pathogenesis

Thought to be caused by capillary bleeding.▪ Major factors:

• Intra-vascular factors‒ Loss of cerebral autoregulation‒ Abrupt alterations in cerebral blood flow and pressure

• Vascular factors

‒ Germinal matrix-vulnerable to hypoxia‒ Reperfusion injury

• Extravascular factors‒ Poor vascular support in cerebral tissue

41

IVH Risk FactorsAbrupt changes in cerebral circulation▪ Rapid changes in PaCO2▪ Rapid changes in aortic pressure

• Rapid infusion of volume expander • Excessive increase in vasopressor

infusion• Noxious procedures

‒ suctioning, PIV insertion, CT insertion, loud noises, aggressive handling

▪ Large PDA with left-to-right shunt▪ Elevated venous pressure from tension

pneumothorax or excessive ventilator pressures

11/6/2018

22

IVH Timing and Progression

▪May begin in utero, but usually begins after birth▪Hemorrhages may be small at first, then progress to larger hemorrhages later

▪Most large or progressive IVH’s begin in the first week of life

Why is this important to the bedside nurse?

43

Symptoms of IVH▪Majority are asymptomatic

• Dx is cranial ultrasound‒4th day 90% detected‒Serial ultrasounds

▪ Timing of onset:• 50% by 24 hours of age• 80% by 48 hours of age• 90% by 72 hours of age• 99.5% by 7 days of life• 20 to 40% have progression of the hemorrhage over 3

to 5 days44

11/6/2018

23

Acute/ Catastrophic Presentation

▪Clinical signs include:• Bulging anterior fontanelle/split sutures• Decreasing hematocrit• Bradycardia• Hypotension (or reactive hypertension)• Temperature instability• Glucose intolerance or hypoglycemia• Metabolic acidosis

45

Surveillance for Intracranial Hemorrhage

▪ Stable neonate• HUS at end of the first week of life• If HUS normal repeat at 1 month of age• Repeat HUS sooner if infant has a predisposing event

or deteriorates‒ Weekly head circumference measurements

‒ 32 weeks 1.4 mm width

‒ 36 weeks involute

48

11/6/2018

25

IVH▪ Diagnostic:

• Cranial ultrasound (serial) – Papile Classification (1988):

‒ Grade I: Subependymal hemorrhage in the periventricular germinal matrix.

‒ Grade II: Partial filling of the lateral ventricles without ventricular dilation.

‒ Grade III: Intraventricular hemorrhage with dilation

‒ Grade IV (PHI): Intraventricular hemorrhage with parenchymal involvement or extension of blood into the cerebral tissue

• LP to rule out septic shock or meningitis

Potentially Better Practices to Prevent Brain Injury

McLendon et al. Pediatrics, 2003; Carteaux, et al, Pediatrics, 200379

1. Antenatal steroids & magnesium2. Optimize management and delivery at center with a NICU3. Early management by a Neonatologist/NNP4. Minimize pain and stress

1. Avoid pain and stress2. Developmental Care

5. Optimal positioning (midline)6. Treat hypotension7. Judicious indomethacin use8. Optimize respiratory management9. Limit sodium bicarbonate use10. Use post-natal dexamethasone judiciously

Delayed Cord Clamping (DCC)• ACOG Committee Opinion, Number 684, January 2017

• DCC in vigorous term and preterm infants for at least 30-60 seconds after birth

• DCC increases hemoglobin levels at birth and improves iron stores

• Improves transitional circulation

• Decreases need for pRBC transfusion• Lowers incidence of NEC and IVH• Does not increase risk of postpartum hemorrhage• What is done in your center?

41

The “Golden” Hour (Delivery Room Toolkit)▪ Based on principles from cardiovascular and emergency medicine

▪ First hour of life is a time of critical transition and adaptation

▪ Management has been show to impact long term outcomes

▪ Structured focus on thermoregulation, minimizing energy consumption, and respiratory support

▪ Measurable data points include: time to admission, admission temperature, admission glucose, initiation of IV fluids with glucose and amino acids

▪ What does your “Golden” hour look like?

81

Castrodale, V. and Rinehart, S. (2014). The Golden Hour: improving the stabilization of the very low birth-weight infant. Advances in Neonatal Care, 14(1):9-14.

Neutral Head Positioning▪ First studied in adults in the 1980s

▪ Infants less than 32 weeks are positioned in neutral midline position with the head of the bed tilted upward for 72 hours

▪ Goal: to reduce alterations in cerebral blood flow associated with turning of the head from side to side in efforts to reduce the incidence of IVH

▪ Thoughts?

▪ Key stakeholders? Equipment needs?

▪ How is this audited?

82

11/6/2018

42

Cerebral blood flow

▪ELBWs have impaired cerebral autoregulation

▪Everyday ICN tasks that affect Cerebral Blood Flow (CBF)

•Diaper changes

•Suctioning

•Blood sampling

▪Can we prevent harm to our patients?

83

Blood Sampling

▪Evidence has shown blood sampling techniques from UACs affect cerebral blood flow and oxygenation

▪20 second vs. 40 second push-pull

84

11/6/2018

43

Permissive hypotension

▪ Current practice

▪ Preterm infants with a MAP<GA often have no

clinical signs of shock

• Presumably have adequate tissue oxygen

delivery

• May not need treatment.

85

Ahn, S., Kim, E., Kim, J., Shin, J., Sung, S., & Jung, J. et al. (2012). Permissive Hypotension in Extremely Low Birth Weight Infants (≤1000 gm). Yonsei Medical Journal, 53(4), 765. http://dx.doi.org/10.3349/ymj.2012.53.4.765

Permissive hypotension

▪ Numerical blood pressure value lower than gestational

age should not be used as the only indicator for

treating early period hypotension

▪ Hemodynamic status should be included in

assessment

• unstable vital signs, impaired perfusion, skin color,

capillary refill rate, urine output, blood lactate level,

and acidosis

86

11/6/2018

44

Treatment for hypotension▪ Treat the cause!

• Normal Saline

• PRBCs

▪ Medications

• Dopamine

• Hydrocortisone

87

Reperfusion injury▪ Tissue damage caused when

blood supply returns to the tissue

after a period of ischemia or lack

of oxygen

▪ Absence of oxygen and nutrients

from lack of blood supply during

ischemic insult

▪ Restoration of circulation results

in inflammation and oxidative

damage rather than restoring

normal function88

Premature Infants-Developmental Consequences

Evolution of developmental delay is evident by term equivalents:

Compared to full term infants:

• Poor orientation (p<.001)

• Poor tolerance of handling (p<.001)

• Poor self regulation (p<.001)

• More sub-optimal reflexes (p<.001)

• More stress (p<.001)

• More hypertonicity (p<.001)

• More hypotonia (p<.001)

• More excitability (p=.007)

Psychiatric Disorders and General Functioning in Low Birth Weight Adults: A Longitudinal Study

(Lærum et al. 2016)

▪ Term SGA group increase in the estimated probability of psychiatric disorders from 9% to 39%

▪ At 26 y/o, preterm VLBW and term SGA had increased psychiatric disorders (36%, 38% vs 14%)

▪ Both low birth weight groups had lower educational level and functioning scores than controls and a higher frequency of unemployment and disability benefit.

91

Neuro-developmental Care▪ Efforts focused on promoting positive neuronal organization

and myelination

• Cluster care

• Reduce environmental stimuli

• Positive touch

• Early skin to skin

• Procedural support

▪ Nutrition

Offsetting stress with POSITIVE experiences▪ Stressful experiences in NICU are inevitable

▪ How do we provide positive experiences?

• Tactile

• Vestibular

• Gustatory

• Olfactory

• Auditory

• Visual

▪ How do we document this?

97

Sleep Preservation▪ Touch times should allow for ample sleep

• Promote & protect sleep cycles• Never wake a baby in REM sleep

▪ Sleep deprivation or disruption leads to:• Disordered sensory system• Decreased learning and memory capabilities

• Smaller adult brain• Irritability
